Why do I still have a fever when the rash appears?

The rash on children is also called roseola infantum, which is a common viral disease in early childhood. Roseola infantum can easily cause the child to have a fever or a rash on the skin. Generally, the rash will appear during the baby's fever, and it is also common for the body to have a fever after the rash appears. This is because the body's hormones have not returned to normal as the body gradually improves.

Why does a child still have a fever after having a rash?

Roseola infantum usually causes fever for three or four days in a row, and the rash will appear only after the fever subsides. However, many parents often take their children to the hospital every day during the days when their children have a fever, which is not advisable. If the diagnosis has been confirmed, the child will gradually get better after three or four days as long as he or she is cared for at home according to the doctor's instructions.

Roseola infantum has an acute onset, and the child is often fine just now but suddenly has a fever in a moment. This is especially true if the child is normal before going to bed but suddenly has a fever at night and the high fever does not go away. Many parents are very worried.

The child will not develop a rash when he has a fever, but will develop a rash after the fever subsides. That is to say, after the child has a continuous fever for 3 to 4 days, the temperature will subside and some rashes will appear on the body. The rashes are light red and the size of a needle tip. They are first seen on the trunk and then spread to the whole body, most commonly on the trunk, and can also be seen on the face and neck. They will disappear in 1 to 2 days, leaving no scars on the skin, so parents do not need to worry.

Roseola infantum is a mild infectious disease with weak contagiousness. A person only gets it once in his or her lifetime. Adults and even children over one year old will not get it. It only occurs in infants around six months old.

If a child has roseola infantum, he or she should first go to the hospital for a clear diagnosis, follow the doctor's advice, and give the child medicine on time. If there is no major change in the condition, there is no need to go to the hospital every day because of the persistent fever. You should pay attention to giving your child plenty of water, especially hot water or hot rice soup, to make him sweat. Only by sweating can the body temperature go down.

The main symptom of roseola infantum is fever at the beginning, even as high as 39 or 40 degrees, accompanied by diarrhea and other symptoms. After about three or four days, a small rose-red rash will appear after the fever subsides. This is roseola infantum.

Prevention and care

In terms of prevention and care, parents should pay attention to the following points: Children under one year old have not yet developed fully and have poor ability to resist disease, so do not take your children to visit friends or go to public places. Because there are many people in public places, the density of bacteria and viruses in the air is relatively high, so the possibility of children contracting diseases will be greatly increased. Children under one year old must have a regular diet, and pay attention to the intake of vegetables after they can add complementary foods. Traditional Chinese medicine believes that the spleen and stomach are the foundation of a person's acquired constitution. Regular and rich diet and normal food intake can promote the good development and growth of children. When your body becomes strong, your resistance to disease will naturally increase.

During the period of fever in children, they should be given plenty of water, preferably warm water, and no sweet water. Because children have poor appetite when they have a fever, sweet water will further affect their appetite and is not conducive to recovery from the illness. The diet should be light. Fatty, sweet and greasy foods will cause stagnation of Qi and affect the spleen and stomach's transportation and digestion functions. Children are weak during illness and should pay special attention to avoiding wind and cold, and be careful not to sweat in the wind, as this will attract new evils and cause recurrence of the disease. When a child has a fever and sweats, you can wipe the child with a warm, wet towel or a soft, dry towel. This will both dissipate heat and provide comfort.
